X Layer completes PP upgrade and starts OKB Gas Token economic model optimization

This upgrade also includes an optimization of the OKB Gas Token economic model. OKB will continue to serve as the sole gas and native token for the X Layer. OKX will destroy all 65,256,712.097 OKB previously repurchased and reserved. Following this, the OKB smart contract will be upgraded to remove the issuance and manual destruction functions, fixing the total supply at 21 million.
